Abstract

Concrete is the main building unit used in infrastructure and buildings, including dams, swages, and
sewage pipes. The main problem in the concrete used in the sewerage pipe or the water treatment system
is the erosion when concrete becomes subjected to different pHs. This study’s objective is to evaluate and
model the effects of various pHs on plain concrete and concrete modified with fly ash. Water to cement
ratio and time of curing were taken as independent variables in the experiment. The main dependent
variables are the strengths of compression and tensile of the concrete. From the over 900 data collected,
the w/c was ranged between 0.3-0.5. The compression strength varied from 0-88.6 MPa and tensile
strength ranged from 0.5-5 MPa. Direct correlations between compression strength and w/c, curing time,
pH value and fly ash precentage were not found. From the Nonlinear Model ( NLM) parameters, fly ash
percentage has a positive effect on the concrete resisting the different pH values. However, FA% content
should not exceed 25% because it will cause the cement to lose its bonding qualities. FA might reduce the
rate of penetration of the chemicals and make the concrete resist the chemicals to penetrate further into
the interior of the concrete.
